2-Methyl-3-(2-methylphenyl)-4-oxo-3,4-dihydroquinazolin-8-yl 4-bromobenzene-1-sulfonate

Abstract

The title mol-ecule, C 22H 17BrN 2O 4S, has a twisted U shape, the dihedral angle between the quinazolin-4-one and bromo-benzene ring systems being 46.25 (8)°. In order to avoid steric clashes with adjacent substituents on the quinazolin-4-one ring, the N-bound tolyl group occupies an orthogonal position [dihedral angle = 89.59 (8)°]. In the crystal, mol-ecules are connected into a three-dimensional architecture by C - H⋯O inter-actions, with the ketone O atom accepting two such bonds and a sulfonate O atom one.
